To understand how electoral reform affects political outcomes, one needs to assess its total effect, incorporating how the reform affects the outcomes given the political status quo (the mechanical effects) and the additional reactions of political agents (the psychological effects). This article proposes a framework to ascertain the relative magnitude of mechanical and various psychological effects. The empirical approach is based on pairwise comparisons of actual and counterfactual seat allocation outcomes. It uses the design to analyze a nationwide municipal electoral reform in Norway, which changed the seat allocation method from D’Hondt to Modified Sainte-Laguë. The study documents clear psychological effects.

The European Union and the Return of the Nation State


This book explores the complex and ever-changing relationship between the European Union and its member states. The recent surge in tension in this relationship has been prompted by the actions of some member state governments as they question fundamental EU values and principles and refuse to implement common decisions seemingly on the basis of narrowly defined national interests.
